COMSOL 4.3 Update 2

Released August 23, 2012.

This update corrects several bugs and stability issues in COMSOL 4.3. The update is cumulative; that is, it applies to both COMSOL 4.3 and COMSOL 4.3 Update 1 and includes all updates from the previous Update 1.
Update Details.

We recommend that you reapply the software update after installing new add-on products to an existing COMSOL 4.3 installation.

Installation

Check your version

Make sure that you run COMSOL version 4.3.0.151 or later. On the Help menu,
click About COMSOL Multiphysics to check your version. If you have an
earlier build number, contact your COMSOL sales representative to get
the official release of COMSOL 4.3 before you proceed.

Install

Before you proceed with the installation, make sure to exit any running COMSOL process.

Windows

Run the downloaded .exe-file to extract the update to the COMSOL 4.3 installation directory, for
example C:\Program Files\COMSOL\COMSOL43.

Linux

Copy the downloaded .zip-file to the COMSOL 4.3 installation directory:

cp comsol_4.3.0.233_linux.zip [installdir]/comsol43

where [installdir] is
the root of the installation, for example /usr/local. Unzip it by the
commands:

cd [installdir]/comsol43unzip -o comsol_4.3.0.233_linux.zip

If you have not disabled SELinux, run the following command:

chcon -t textrel_shlib_t [installdir]/comsol43/lib/[platform]/lib*

where platform is glnx86 or glnxa64.

Macintosh

Double-click the downloaded .dmg file to mount the disk image. In the Finder, open the mounted disk and double-click the COMSOL installer icon. Select your COMSOL installation folder, usually called COMSOL43.

Check your installation

Start COMSOL Multiphysics.

On the Help menu, click About COMSOL Multiphysics.

Check that the version number is 4.3.0.233 (If not, the installation did not succeed).

Update Details for Update 2

COMSOL Multiphysics

Corrected display of results tables for parametric sweeps.

Fixed mesh generation errors that could occur when resolving small domains or when measuring faces.

Corrected handling of scale factor for deformed shape plots.

Improved stability and backward compatibility.

Improved stability in SOR solver.

Fixed problem with the dogleg solver that could prevent the solver from completing.

Improved stability in the report generator.

Corrected adaptive mesh refinement for time-dependent 1D models.

Moving a results feature node now gives a correct Java history.

Corrected selection handling for models with more than one Particle Tracing interface.

Corrected error in the eigenvalue solver that could cause COMSOL to shut down.

Parametric lines and surfaces can now be evaluated for more than one solution number.

Fixed error that could cause COMSOL to become unresponsive during interactive evaluation in the graphics window for a plot group that contains a Max/Min marker plot.

AC/DC Module

Tensor components for relative permeability are now displayed correctly.

Boundary conditions now include selection of coordinate systems when applicable.

Revolution data sets are no longer created for planar 2D models.

Corrected the norm of the magnetic field in the 2D Magnetic Fields interface.

Global matrix evaluation for ports and terminals now displays correctly in all cases.

Axisymmetric 2D models solving for magnetic fields now work correctly also when solved on a moving mesh.
